RICHARD MCINTIRE, OF CHICAGO, ILLINOIS,ASSIGNOR TO INTERNATIQNAL HAR-VESTEB CGMPANY OF NEW. JERSEY, A CORPORATION OF NEW JERSEY.

POWER-TRANSIVLISSION MECHANISM.

Specification of Letters Patent.

Patented Feb. 1,1916.

To all whom it may concern Be it known that I, RICHARD E. MCTNTIRE, acitizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvementsin Power-Transmission Mechanism, of which the following is a full,clear, and exact specification.

My invention relates to mowing machines, and in particular to the powertransmission mechanism between the traction wheels and the cuttingapparatus, such mechanism including a clutch operative in connectionwith the power transmission mechanism to cause engagement ordisengagement of associated parts of the mechanism.

The objects of my invention is to provide a construction that is simple,cheaply made, durable and efficient in operation. I attain these objectsby means of the mechanism illustrated by the accompanying drawings, inwhich Figure 1 is a top plan view of part of the main frame ofa mowingmachine and having my invention forming a part thereof; Fig. 2 is avertical sectional elevation of part of Fig. 1 along line A-B; and Fig.8 is an end elevation of part of Fig. 2 in the direction of the arrow C.

The same reference characters designate like parts throughout theseveral views.

1 represents a part of the main frame of a mowing machine, 2 one of thetraction wheels journaled upon a transverse axle 3 and having a gearmember secured thereto that engages with a pinion A integral with abearing sleeve that is mounted upon one end of the cross shaft 5. Thissleeve is provided with an oil chamber or reservoir 5 surrounding theshaft, the sleeve being connected with the shaft by means of a pin 6 andhaving a cylindrical bearing portion 7 journaled in a bearing box 8forming part of a rearwardly projecting arm 9 integral with the mainframe 1 and an angular portion 10 extending axially from the part 7. Theopposite end of the shaft 5 is journaled in a bearing box 11 formingpart of an arm 12 extending rearwardly from the frame 1.

13 represents a gear wheel journaled upon the shaft between the bearingbox 11 and the angular extension 10. The gear wheel 13 is provided witha clutch member 14. that is adapted to engage with a clutch member 15slidably mounted upon the angular portion 10 of the sleeve member andhaving .a

circumferential groove 16 that receives a clutch shifting fork 17, thatis carried by a rod 18, that is slidably mounted upon the arm 12. v

19 represents a pinion. secured to the rear end of a longitudinallyarranged shaft 20 and intermeshing with the gear wheel 13.

The clutch member 15 is movable into and out of engagement with the gearwheel 13 in a common way.

The bearing boxes 8 and 11 are provided with bronze bushings 21 and 22respectively having oil ducts communicating with a source of supply, and23 represents a collar secured to the shaft 5 and having a counterboreportion that receives a washer 26 and balls 27 that are disposed betweenthe washer 26 and a washer 28 adjacent the bearing box 11. The bearingportion 7 is provided with an oil duct 29 that communicates with theduct in the bushing intermittently, and one or more ducts 30 near theopposite end of the oil chamber that permit oil to flow from thereservoir 5 to the bearing as the sleeve revolves.

Although I have illustrated and described one embodiment of myinvention, modifications may be made therein without departing from thespirit of my invention as set forth in the appended claims.

What I claim as my invention, and desire to secure by Letters Patent,is:

1. A power transmitting device comprising a pinion having integraltherewith a cylindrical chambered bearing member terminatmg in anangular extension.

2. A power transmitting mechanism including, in combination, a pinionhaving integral therewith a cylindrical chambered bearing memberterminating in an angular extension, and a bearing box surrounding saidbearing member.

8. A power transmitting mechanism including, in combination, a pinionhaving integral therewith a cylindrical bearing member terminating in anangular extension, and a clutch member slidably mounted upon saidangular extension.

4-. A power transmitting mechanism including, in combination, a pinionhaving integral therewith a cylindrical chambered bearing memberterminating in an angular extension, and a shaft extendinglongitudinally through said extension and bearing member.

5. A power transmitting mechanism including, in combination, a shaft, apinion secured to said shaft, said pinion having integral therewith acylindrical bearing member terminating in an angular extension, a gearmember journaled upon said shaft and provided with clutch teeth, and aclutch member slidably mounted upon said angular extension and adaptedto engage with said clutch teeth.

6. In a mower, a frame having parallel extensions thereon, alinedbearing boxes carried on said extensions, a shaft extending through saidbearing boxes, a gear rotatably mounted on said shaft between saidboxes, a pinion journaled in one of said bearing boxes having an angularextension extending into close proximity to said gear, said pinion andextension inolosing one end of said shaft, cooperating clutch mechanismcarried on said 'gear and said extension, driving mechanism for saidpinion carried by said frame, and driven mechanism operatively connectedto, said gear and journaled on said frame.

In testimony whereof I aiiix my signature, in'the presence of twowitnesses.
